/* ============================================================
   马卡龙轻量化风格 · 设计变量
   ------------------------------------------------------------
   规则：
   1) 卡片一律「纯白 + 无边框 + 极浅阴影」，靠留白和阴影分层，不靠描边；
   2) 所有彩色都从下面六组马卡龙里取，浅底配深字，不出现刺眼的饱和色；
   3) 状态色只有三档语义：ok（对/已交/优）、half（半对/待定）、bad（错/缺/待提）；
   4) 组件里不要再写死色值，一律引用这里的变量。
